LIFTING-SLING.

pulling instrumentalities for binding and holding such articles and materials as can be embraced by a cham or similar fiexlble bindmg member.

It is an object of the invention to provide a device of that character that includes means whereby free portions of the chains may be fastened easily in place after being drawn snugly by hand around a load and that operates in response to lifting or pulling stress further to bind the chains to the load.

When read in connection with the description herein, the details of construction and arrangement of parts contemplated by the invention will be apparent from the accompanying drawing, forming part hereof, wherein an embodiment of the invention is disclosed, for purposes of illustration.

l/Vhile the disclosures herein exemplify what now is considered to be a preferable embodiment of the invention, it is to be understood that it is not the intention to be limited necessarily thereto in interpretation of the claims,as modifications and adaptations within the limits of the claims can be made without departing from the nature and spirit of the invention.

Like reference-characters refer to corresponding parts in the views of the drawing, of which- Figure 1 is a side elevation; and

Fig. 2 is a front elevation.

Having more particular reference to the drawing, 3 designates a base-plate arranged to rest on the load to be bound and lifted or pulled.

Flanges 4, of upright plates or side members 5 spaced from each other, extend sub stantially at right angles from those members, and they are welded, bolted, or otherwise suitably fastened to the base-plate. The plate and members constitute the frame of the device.

A shaft 6 is journaled in the side members Specifieationof Letters Patent. Patgnted Sept. 21 1920 Application filed. November 25, 1919.

next above the base-plate. Mounted loosely on that shaft outside of those members are sleeves 7 each of which has a radial extension 8 formed with a bifurcated free end 9 in which is held by a pin 10 an end link of a chain 11 or other suitable flexible binding member. Wheels 12, one fast on each end of the shaft 6 outside of a sleeve 7 have peripheral recesses or seats 13 conforming in shape to and arranged to take the chains used, abutments 13 engaging the links lying fiat and preventing the chains 7 from slipping off the wheels.

A gear 14, fast on shaft 6 between the side members, is in mesh with an intermediate gear 15 on a shaft 16 carried by those mem-- bers. Gear 15 meshes with a toothed terminal segment 17 of an arm 18 having at its opposite or free end an eye 19 adapted to be engaged with a lifting-hook or the like, the arm being mounted for swinging move- Irjnent on a shaft 20 carried by the side memers.

l/Vhen a load, such as timbers for example, is to be bound and lifted or pulled, the baseplate 3 is lowered to and is rested on the load, and the chains extending from the extensions 8 are passed under and around the load and over the wheels 12 and into the peripheral seats thereof. V

Before the chains are drawn as tightly into tensions 8 have taken, for example to the position shown by dotted lines in Fig. 1. Then when stress. is imposed on the arm by a member in engagement with eye 19, the arm will be drawn back toward the axial line of the device, and will operate, through the instrumentality of the segment and gears, further to bind the chains to the load. As soon as the load has been moved to the place desired and stress released from the arm, the chains may be loosened by swinging the arm back to laterally displaced position and then removed from the wheels.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A lifting-sling comprising a frame having means of connection for a flexible load-binder, a rotatable shaft, a winding member fast on said shaft arranged to have such a load-binder engaged therewith, an operating member on said shaft, an arm swingable on said frame arranged for connection with a pulling element, and means interposed between said arm and operating member whereby said Winding member is rotated when said arm is swung.

2. A lifting-sling comprising a frame having means of connection for a flexible load-binder, a rotatable shaft, a winding member fast on said shaft arranged to have such a load-binder engaged therewith, a fast on said shaft, an arm swingable on said frame arranged for connection with a pulling element and having gear-teeth, and a gear in mesh with said teeth and with said winding-member-shaft gear.

3. A lifting-sling comprising a frame, a rotatable shaft thereon, a sleeve loose on said shaft having means of connection for a flexible load-binder, a winding member fast on said shaft arranged to have such a loa'd b'in'der' engaged therewith, an operating member on said shaft, an arm swingable on said frame arranged for connection with a pulling element, and means interposed between said arm and operating member whereby said winding member is rotated when said arm is swung.

41-. A lifting-sling comprising a base member, spaced frame members extending therefrom, a' shaft rotatable in said frame members, means of connection for a flexible loadbinder, a winding member fast on said shaft arranged to have such a load-binder wound thereover, a gear fast on said shaft between said frame members, an arm swingably mounted between said frame members arranged for connection with a pulling element and having gear-teeth, and a gear journaled between said frame members in n esh with said teeth and with said winding-member-shaft gear.

5. A lifting-sling comprising a base member, spaced frame members extending upwardly therefrom, a lower shaft rotatable in said frame members, a sleeve loose on said shaft outside of each frame member having means of connection for a flexible loadbinder, a winding member fast on said shaft outside of each frame member arranged to have such a load-binder engaged therewith, a gearfast on said shaft between said frame members, an intermediate shaft on said frame members, a gear on said intermediate shaft in mesh with said lower gear, an upper shaft on said frame members, and an arm swingably mounted thereon arranged for connection withv a pulling element and having gear-teeth in mesh with said intermediate gear.

In testimony whereof I afiixmy signature.
